The History of Chemistry

• 183: New World Coming

  I give a brief history of finding planets around other stars, including discovery by gravitational wobbling, dimming as the planet crosses in front of its star, and even seeing an actual planetary image by blocking the star's glare. I discuss what sort of spectroscopic signals might be present for life in a planet's atmosphere. Finally I offer some planets already detected whose temperatures appear to be in the range of terrestrial life, and what's in their atmospheres.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 182: It's Life, Jim, But Not As We Know It

  We take an imaginary trip around our Solar System to hear the history of chemical attempts to find life, starting in the late 1950s. Among our stops on the tour include Venus, Mars, Europa, and Titan. Included in the tour are temperature measurements, spectroscopic views, gas chromatography, radioactive labeling, photographs, electrical conductivity, and more.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 181: A Work in Progress

  In which we bring research into molecular machines up to date. We discuss fuels, specifically what chemists think are the best kinds of fuels to power these little molecules. We discuss what makes a molecular machine different from a regular-sized machine. We also talk about molecular machines as a subset of "molecular devices." Finally, we mention a poll for researchers that IUPAC has set up to help chemists define what a molecular machine really is.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 180: Farm to Market

  Instead of just digging in the ground to extract minerals, over the past half-century scientists have begun to explore agriculture of hyperaccumulating plants to pull elements--including heavy metals--out of the topsoil. We explore the recent history of this topic, its advantages and pitfalls.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 179: This Episode is Meta

  The History of Chemistry is itself an academic discipline, and in this episode we explore the history of chemical history. We start with chemist Thomas Thomson, and work our way forward in time, through the various books on the subject, the founding of the History of Chemistry Section of the American Chemical Society, various chemical-history journals, the Science History Institute, and the Royal Society of Chemistry's Historical Group.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!
